3M™ Glass Bubbles for Paints and Coatings

Engineered additives for a new generation of high performance paints and coatings.

3M™ Glass Bubbles are lightweight/high-strength hollow glass spheres, used as alternatives to conventional fillers in a variety of paints and specialty coatings, including spackling, caulks, adhesives, roof coatings and more.

These versatile additives are widely used to reduce formulation weight and lower viscosity. But they can also improve abrasion resistance and reduce thermal expansion. Eliminate shrinkage. Provide a better surface for sanding. And allow you to achieve higher filler loadings, to displace high-cost resins – without diminishing product performance.

3M™ Glass Bubbles are available in a wide range of strengths, densities and average particle sizes, to meet various performance and processing requirements. The following chart lists the 3M Glass Bubbles most commonly used in paints and specialty coatings formulations.
